These two cases have very different interpretations.
WebbIt is often of interest to assess how much of the effect of an exposure on a response is mediated through an intermediate variable. However, systematic approaches are lacking, other than assessment of a surrogate marker for the endpoint of a clinical trial. We review a measure of "proportion explain …
Webb3 aug. 2011 · I want to say that the total effect of y on x is -0.127, and the specific indirect effect mediated by m is -0.044, therefore 34.6% of the total effect of x is mediated by m.
